原生地・分布（英語）:

説明（英語）: Genus of more than 1,000 species of shrubs, climbers, and small trees from very variable habitats throughout tropical regions of the world. Many have a pungent aroma, and some, including P. nigrum, are grown as spice crops in tropical regions. They bear alternate, asymmetric, very variable, but often narrowly to broadly ovate to rounded green leaves, heart-shaped at the bases, on stems that are swollen at the nodes. Cylindrical spikes of small (often unisexual) flowers without petals or sepals are followed by single-seeded fruit. In warm, humid, tropical areas with heavy, well-distributed rainfall, peppers are grown in fertile soils, with the shade and support of trees. Fruits are harvested at different stages of ripeness for different uses: dried, green mature fruit for black pepper; ripening green fruit for pickled pink peppercorns; ripened, red or yellow fruit (soaked to remove the outer layer of skin) for white pepper. In temperate zones, P. nigrum is grown in a conservatory or warm greenhouse; it may bear fruit under glass. Grow outdoors only in tropical areas.
